[Phacoemulsification of cataract in patients with high myopia]

We conducted a study for the purpose of developing a phacoemulsification technique for patients with high myopia optimized for the specificity of myopic eye. The study involved 124 (165 eyes) patients with high myopia and cataract. The lens density in operated patients was of degrees II-IV according to Buratto. The anterior-posterior axis of the eyeball ranged from 26.5 to 34.00 mm. the patients were shared between the experimental (92 eyes) and control (73 eyes) groups with respect to a used surgical technique. A modified procedure was applied in the experimental groups and the basic technique was used in the control group. The time of lens extraction, the volume of used irrigation liquid and the frequency rate of intra- and postoperative complications were the criteria in efficiency evaluation. The study showed the modified surgical procedure of phacoemulsification to ensure a better visualization, to reduce the load on the lens ligamentous apparatus and to facilitate, as much as possible, manipulations made on the lens nucleus of myopic eye; it also cuts the time of cataract lens extraction, which ensures a less volume of used irrigation liquid.
